Figure 111. Here is the completed axle assembly. The studs were purchased from the local Oreilly's Auto Parts. They are cheap and plentiful. We used the hydraulic press to install them. Not shown here, but the bearing was wrapped in a shop towel and tape ran around it to keep dirt out of it until it is time to install it into the axle housing.

Figure 112. There are many good gear companies out there, after much searching and looking and reading, we decided to go with Revolution Gear for the 4:88 ring and pinion for the rear axle. While the Jeep currently has 32 inch tires, the 4:88 gears will allow us to upsize a modest amount later if we want, and if we don't, we still get a benefit from a little deeper crawl ratio.

Figure 113. We also went with the master install kit from Revolution Gear, which uses good quality Koyo bearings. The only failing we can see with the kit is a small selection of shims for the carrier and pinion depth. It seems a lot of the manufacturers are not providing a large shim assortment with their kits, was we also have a Yukon shim set, and it was not any better.

Figure 114. These are the measurements for the old shims that were in the axle. NRGS is Non-Ring Gear Side of carrier. RGS is Ring Gear Side of carrier, PP is Pinion Preload, and PD is Pinion Depth. We were going to use these as the baseline to start the shims on the new carrier and gears, but these numbers are way off of what Dana recommends to start with, which is .035. We set up .035 shim packs and started setting up the gears from there.
